• Communicate risks, blockers, and concerns promptly while adapting to evolving requirements and priorities.

What Success Looks Like

• Effective participation in code reviews, technical discussions, and team planning.
• Accurate system and integration configuration using approved tools and patterns.
• Prompt communication of risks and steady growth in technical and business knowledge.
• Positive contribution to production stability, documentation quality, and overall team effectiveness.

Why Join Us

• Join a growing core development team building and improving business-critical internal systems.
• Work on meaningful operational challenges across construction execution, workforce processes, integrations, reporting, mobile workflows, and platform modernization.
• Develop your skills through collaboration with experienced developers, technical leadership, and business stakeholders.
• Contribute to a team culture that values accountability, learning, practical problem-solving, and coding excellence.
• Receive a competitive salary and benefits package.
• 3-5 years of professional software development experience.
• Proficiency in JavaScript and React for front-end development.
• Experience with C# and .NET for back-end development.
• Strong SQL skills and hands-on experience with PostgreSQL and/or Microsoft SQL Server.
• Experience building or supporting RESTful APIs and modern web applications.
• Experience using Entity Framework Core or a comparable object-relational mapping framework.
• Strong troubleshooting skills and experience supporting production systems.
• Ability to understand how application components, services, integrations, and data fit together.
• Ability to independently deliver assigned features while following technical direction and established standards.
• Clear communication, sound judgment, attention to detail, and effective collaboration skills.
• Comfort working in a fast-paced, deadline-driven environment with changing priorities.
